Features and advantages

1.DC control box has MPPT power tracing function, which is higher than normal tracing effect 5-10%
2.DC control box has anti-connection function of DC power, if it is connected, the control box will alarm. Control box without this function, if the power supply is connected back to the positive and negative, it is likely to burn out the control box.
3.All pump bearings are authentic NSK bearings, low noise, high quality, long life.
4.SS 304 stainless steel for impeller. And many factories do 3-inch well pump, with plastic impeller, wear fast, short life.
5.Fid series well pump, our matching control box, has the function of downhole waterless shutdown. When there is a shortage of water in the well, the control box will stop the pump automatically, and after 30 minutes the pump will automatically detect whether there is water. Many pumps and control boxes on the market do not have this function, so if there is no water underground, then the motor is likely to be burned out.
6.DC series control box can automatically detect whether the power supply is solar panel or battery, if detected solar panel power supply, start MPPT power tracing function; if detected is battery, with low-voltage, under-voltage protection function.
